GetProjectionMode

This function gets the projection mode of a camera.

Syntax

Returns

Returns the camera's projection mode. This can be one of the following values:
Camera::Orthographic: flat 2D rendering.
Camera::Perspective: 3D perspective rendering.

Example

--Create a window
window = Window:Create()
context = Context:Create(window)
world = World:Create()
camera = Camera:Create()
camera:Move(0,0,-3)
local light = DirectionalLight:Create()
light:SetRotation(35,35,0)

model = Model:Box()
model:SetColor(0.0,0.0,1.0)

while true do
        if window:Closed() or window:KeyHit(Key.Escape) then return false end

        model:Turn(0,Time:GetSpeed(),0)

        if (window:KeyHit(Key.Space)) then
                if (camera:GetProjectionMode()==Camera.Orthographic) then
                        camera:SetProjectionMode(Camera.Perspective) 
                        camera:SetZoom(1) 
                else
                        camera:SetProjectionMode(Camera.Orthographic) 
                        camera:SetZoom(100) 
                end
        end

        Time:Update()
        world:Update()
        world:Render()

        context:SetBlendMode(Blend.Alpha) 
        context:DrawText("Projection mode: "..camera:GetProjectionMode(),2,2) 
        context:DrawText("Zoom: "..camera:GetZoom(),2,22) 

        context:Sync()
